Either you remove 2 fields from one row with CSS, or you re-align the order in PHP if you remove just one field from one row.
For that city, area, country – alignment you’ll need to modify the php template, and add the the half_form and half_form half_form_last order classes to the fields that have remained in your list, so they are ordered correctly.
Correctly means: half_form class for 1st column. half_form half_form_last for 2nd column (see screenshot).
This change will need to be saved in a list of custom changes so you know what you did, as they’ll be overwritten if you do theme update.
